Helium 3.0

Today, at the centre of our galaxy, dwell small colonies of a most extraordinary species – humans. Snatched from planet earth by slave traders they have a habit of escaping and finding more of their own kind. Now their unique qualities have begun changing the course of galactic history.
Fourteen-year-old Mervyn Bright possesses no special powers or advantages. He has courage, tenacity, and three close friends from the Space Academy: Loren, a brilliant but despised out-worlder, Tarun, heir to a once-powerful dynasty, and Aurora, niece to the embattled Patriarch. Together they make a formidable team.

I think you are trying to introduce too many things at once. Also, I don't undersrand why they are jumping onto a dart or the importance of the Academy, whatever it is. It's a little too much to take in at once.
